Irene makes 4 2/3 cups of pancake batter . she splits the
kvv77 [185]

Answer:


Step-by-step explanation:

An estimate is usually a guess, but I somehow think that's not what you want.

She starts with 4 2/3 cups of batter. When she divides it into two, one of the batters has 2 1/4 cups. That's the one she puts blueberries in.

The other batter is the one you are interested in. How big is it?

Estimate: One

The estimated size would be 4 2/3 - 2 1/3 = 2 1/3 which is an estimate. It is just taking the closest number to use so you don't have to grab your calculator.

Actual Size: Two

4 2/3 - 2 1/4 is the size of the second batter. Since 2/3 is greater than 1/4 you need only subtract the whole numbers and then the fractions.

<em><u>Whole number subtraction:</u></em> 4 - 2 = 2

<em><u>Fraction subtraction:</u></em> 2/3 - 1/4

Find the Lowest common multiple between 3 and 4: It is 12. 3 and 4 are prime to each other. They have nothing in common.

  • 2/3 to 12s: (2*4)/(3*4) = 8 / 12
  • 1/4 to 12s: (1 *3) / (4*3) = 3/12
  • 8/12 - 3/12 = 5/12

So the actual size of the batter containing the walnuts is 2 5/12

Plz do it on paper and plz send the work to me plz thank you
Lelu [443]
Its as simple as length times breath there for it is 7/9 times 6/5 which has a common denominator of 45 so now it is 7/45 and 6/45 and then we say how many times did we multiply the denominator to get to 45 and use that number to multiply the numerator so now we have 35/45 and 54/45 and if you times both of them together you get 14/15 as a final answere
